- This paper thoroughly investigates influences of six orifice chamber configurations on performance characteristics of aerostatic thrust bearings under various operating conditions using the computational fluid dynamics approach, further supported by experiments. The obtained results show that there are many differences in performance behaviours of the aerostatic thrust bearing with different orifice chamber shapes. Further analysis reveals that the pressure depression, gas vortices, and turbulent intensity are all weakened with decreasing air film thickness, while load capacity of the bearing slightly decreased with increasing rotational speeds of the spindle. The findings are critical for design of high precision aerostatic bearing spindles.
